The last couple of nights, when i turn on full beam, which includes 2 bumper mounted spots and 4 55w spots on a light bar, my radio momentaraly goes dead then turns on again. Its hard to tell but they seem to be flickering sometimes aswell. The spots are wired up to the battery with the full beam stalk triggering 2 relays. Any ideas?

take the fuse panel cover off (one fwd of the gear stick) + find the blue headder

replace if it looks / is starting to look like this;

i dont know what systems connect through this headder (couldnt be arsed getting the wiring diagram out once i had eventually found this culpret) but i had a hell of a problem a while ago which included alarm going nutz + lights not working /going off when touching the high beam stalk -resulted in me stripping the whole bulkhead down tracing the wires!. if i wiggle this my radio goes off too.

not sure if its an excess of current flowing which slowly melts this plastic cap but once it starts, the burning fouls the pins + causes problems with the lights

hope this helps

Thanks D. Will have a look tomorrow to see if anything looks amiss but I cant recall having one of those. I forgot to say its an 88 200tdi 110.

Do they, as in the lights and radio, share an earth?

may not have the blue headder if its an 88 but something similar maybe?

Everyone said my problem was an earth but having stripped the dash out down to the firewall, couldnt pinpoint it!

Click to expand...

Probably not supposed too though anything is possible in a depender

Does it only happen when the lights are on?

is any of the stereo loom bunched too tightly behind the unit? -mine is + the display wont light up so can only see what radio station its on in the dark! (when i pull the unit out + set the loom + connectors at the back its fine!)

so if the spots are wired direct to your battery; how old is your battery? -just thinking if the battery's getting on + only just taking enough charge, would the increase in load from putting the beam on cause this effect in an ancillary system with an indirect +ive path.... -im not an auto electrician so just throwing it out there!
